FROM THIS EPISODE

China has provoked Japan and the US to fly military aircraft in disputed air space above the East China Sea. We hear what's at stake on the ground for all three countries. Also, healthcare.gov is up and running better, but there's a long way to go. On today's Talking Point, protesters shouted "revolution" in the streets of Kiev today and occupied government buildings. Their target is President Viktor Yanukovich, who sided with Russia instead of the European Union.

The White House claims it made the self-imposed deadline of November 30 to get the Affordable Care Act website up and running. But not everything is well with healthcare.gov. Noam Levey is congressional and health policy reporter for the Los Angeles Times.

Vice President Biden has arrived in Japan today in the midst of that country's dispute over China's declaration of an expanded air defense identification zone. China's sudden declaration of an “ADIZ” over uninhabited islands has Japan and the US also flying military aircraft in disputed air space. With pilots potentially facing each other at high speeds, there's risk of a collision or a misunderstanding that could lead to unintended consequences. It's all about history and unfinished business from World War II, brought up to date by nationalism, economic competition and power politics. Is it really just between Japan and China? Has the US lost an opportunity to help forge a compromise by weighing in on the side of Japan?

Hundreds of thousands of Ukrainians on the streets of Kiev were chanting "revolution" today, escalating demands that President Victor Yanukovich step down. Yanukovich was the President thrown out by Ukraine's Orange Revolution nine years ago — and then reinstated in a subsequent election. The crowds have been growing since last week, when Yanukovich spurned offers to join the European Union, apparently deciding to accept economic offers from Russia's Vladimir Putin.
